It depends on whether you are learning purely mechanical structure type fixtures or pneumatic and hydraulic fixtures;
The former is relatively easy to learn, and if you study hard, you will be able to master it in 1-2 years. I can get a rough grasp of it. Of course, many commonly used structures in machinery need to be accumulated in the future; jobs are still relatively easy to find, and the salary is estimated to be 5-6 thousand a month after 5-6 years of work. It is estimated that it will go up further. It’s more difficult!
The latter is relatively difficult to learn and requires familiarity with pneumatics and hydraulics; but it is not used by ordinary small factories because the cost of this type of tooling and fixtures is high and it is suitable for large-volume semi-automatic production lines. , but I personally think the prospects are very good. It seems that there is a factory in Ninghai, Zhejiang, that specializes in designing such fixtures for machinery factories (there are very few such companies in China); so compared to the former, it is a little harder to find a job, but of course the level is high. It's not hard to find. As for the salary, I don't know much about the specifics. It shouldn't be a problem if it's 8-9 thousand a month!
